The Only Thing I'd Do in a No-Boys-Allowed Game World, Vol. 1 (novel‪)‬

A dream-come-true scenario quickly becomes a nightmare when a yuri fanboy discovers that he’s been reincarnated into one of his favorite yuri games—as Hiiro, an annoying male character whose only purpose is to get between the heroines. Realizing that he’s destined for ruin in a world where men are at the bottom of the pecking order, Hiiro scrambles to get stronger and avert his fate. But his desperate efforts end up making the game’s heroines—Princess Lapis, Snow the maid, and the protagonist Sakura—fall for him instead of one another! At this rate, he’ll be killed for coming between them! Can Hiiro get the girls interested in one another before it’s too late?
